Law nº 9307, 23 September 1996
– Regarding Arbitration –



Let it be known that the National Congress decrees and I ratify the following law:



Article 1 – Persons capable of entering into contracts may settle through arbitration disputes related to freely transferable patrimonial rights.

Article  2 – At the parties’ discretion, arbitration may be in law or in equity.

§ 1 – The parties may freely choose the rules of law applicable in the arbitration, as long as their choice does not violate good morals and public policy.

§ 2 – The parties may also stipulate that the arbitration shall be conducted under general principles of law, customs, usages and the rules of international trade.



Article 3 – The parties may submit their disputes to arbitration by virtue of the arbitration agreement, which may be in the form of either an arbitration clause or a submission agreement. (compromisso)

Article 4 – An arbitration clause is an agreement by which the parties to a contract undertake to submit to arbitration the disputes which may arise with respect to that contract.

§ 1 – The arbitration clause shall be in writing and it can be inserted in the main contract or in a document to which it refers.

§ 2 – In adhesion contracts, the arbitration clause will only be valid if the adhering party takes the initiative to initiate arbitration proceedings or if it expressly agrees to arbitration by means of an attached written document, or if it signs or initials the corresponding contractual clause, inserted in boldface type.

Article 5 – If the arbitration clause makes reference to the rules of a particular arbitral institution or specialised entity, the arbitration shall be commenced and conducted in accordance with such rules; it being also possible that the parties determine in the arbitration clause itself, or in a stand alone document, the agreed procedure for commencing arbitral proceedings.

Article 6 – In the event of absence of provision as to the method of commencing the arbitration, the interested party shall notify the other party, either by mail or through any other means of communication, with confirmation of receipt, of its intention to commence arbitral proceedings, fixing a date, time and place for signature of the submission agreement (compromisso).

Sole Paragraph: If the notified party fails to appear, or it refuses to sign the submission agreement (compromisso), the other party may file the action provided for in Article 7 of this Law, at the State Court originally competent to decide the case.

Article 7 – Where there is an arbitration clause but one of the parties shows resistance as to the commencement of arbitration, the interested party may request the court to summon the other party to appear in court so that the submission agreement (compromisso) may be signed; the judge shall designate a special hearing for this purpose.

§ 1 – The plaintiff shall specify, in detail, the subject matter of arbitration, including in its motion the document that contains the arbitration clause.

§ 2 – If the parties attend the hearing, the judge shall first try to bring the parties into a settlement. If the judge does not succeed, he/she shall lead the parties to approve, by mutual agreement, the submission agreement (compromisso).

§ 3 – If the parties fail to agree on the terms of the submission agreement (compromisso), the judge, after hearing the defendant, shall determine on the contents thereof, either at the same hearing or within ten days, in accordance with the provisions of the arbitration clause, taking into account the provisions of Articles 10 and 21 § 2º of this Law.

§ 4 – If the arbitration clause has no provision as to the appointment of arbitrators, the judge, after hearing the parties, shall rule thereon, being allowed to appoint a sole arbitrator to decide the dispute.

§ 5 – If the plaintiff, without good cause, fails to appear at the hearing designated for the drafting of the submission agreement (compromisso), the case will be dismissed without judgment on the merits.

§ 6 – If the defendant fails to attend the hearing, the judge, after hearing the plaintiff, shall have the authority to establish the contents of the submission agreement (compromisso), and to appoint a sole arbitrator.

§ 7 – The judge’s decision granting the motion shall be deemed to be the submission agreement (compromisso) itself.

Article 8 – An arbitration clause which forms part of a contract shall be treated as an agreement independent of the other terms of the contract. A decision that the contract is null and void shall not entail ipso jure the invalidity of the arbitration clause.

Sole paragraph – The arbitrator has jurisdiction to decide ex officio or at the parties’ request, the issues concerning the existence, validity and effectiveness of the arbitration agreement, as well as the contract containing the arbitration clause.

Article 9 – The submission agreement (compromisso) is the judicial or extrajudicial agreement by which the parties submit an existing dispute to arbitration by one or more persons.

V – provisions as to the responsibility for the fees and costs involved in the arbitral proceedings; and

VI – stipulation as to the fees of the arbitrator or arbitrators.

Sole paragraph – If the parties establish the fees of the arbitrator or arbitrators in the submission agreement (compromisso), this document will be considered an extrajudicial enforceable instrument. In the absence of such provision, the arbitrator will request the court originally competent to hear the case to rule upon such question.

Article 12 – The submission agreement (compromisso) is terminated:

I – if any arbitrator excuses himself, prior to accepting his appointment, as long as the parties have expressly declared that they will not accept substitution;
